I’ve just purchased a new Mac mini to use V6 rhino on. When it comes to rendering, it seems to exhibit some odd behaviour. Before the purchase I was aware that the rendering ability would be poor.
When it starts a render, the CPU runs at around 85%. Around 2/3 of the way through (image area not time) the CPU speed halves, at 5/6 of the way through the speed again halves. It takes about 10 times as long to do the last 1/3 as it did the first 2/3. On one occasion it became so glacial (it was still going) I had to kill it.
My other observation is that the GPU was doing nothing during the whole process. I really don’t know enough about this to know if this is as should be expected, or I need to change some settings somewhere. The on board graphics is supposed to be the limiting factor, but they only seem to do any work during a render if I move something around on a screen.
If someone could point me towards a guide that would point the way, or if someone with experience in this area could give me a few pointers or just say that that’s as good as it’s going to get, I would be grateful.
I rarely do renders, but some times people seem more able to understand the part rendered with materials, texture and shading, rather than just a screen grab. So it comes in handy on odd occasions.
